Application led March 30,

To all whom t may concern.'

Be it known that we, HENXMUTGHNIK and HYMAN RUDoW, citizens of Austriaand Russia, respectively, residing at.v altimore, State of Maryland,have invented new and useful Improvements in Windows, 'of which thefollowing is a specification.

This invention relates to improvements in windows and especially withreference to the provision of hanging stiles arranged for verticalsliding movement in a window casing and in which -a window sash ispivotally mounted so lthat the sash can be turned on its pivots andarranged in an inclined position, for purposesof ventilation, or can beturned down to a horizontal position to facilitate the v washing of theoutside ofthe panes; one object of theinvention being toeifectimprovements-in theconstruction of the hanging Stiles; anotherdbject is to provide improved means for counter-.balancing the weight ofthe sash :and the hanging stiles and supporting the sash and hangingStiles in any desired position; another object is to provide improvedmeans for adjustably holdin-g the sash: in inclined position and topermit the sash to be turned down to a horizontal position. y Theinvention consists in the construction, combination and arrangement ofdevices hereinafter described and claimed.

.st1les, the pivots 6 ran In the accompanying drawings Figure 1 is aperspective view of a portion of a window sash and a hanging stileconstructed and` arranged in .accordance with our invention and providedwith our improved adjusting links and sash balances, and showing thesash in inclined position.

`g. 2 is a' vertical sectional view.-

Fig. 3 is a transverse sectional view.

`Figs. 4, 5 and 6 are detailed views.

In the embodiment of ou invention we provide a pair of hanging Stiles 1for each window sash 2, the Stiles being arranged on opposite sid of thewindow sash and being arranged also-'for vertical sliding movement inthe usual grooves of the window casin 8 formed [between the strips 4spaced therefrom. he sash is pivoted between the lower ends of thehanging being horizontally ard and projecting outwardly from metalinlaid vplates 7 which are secured in rabbets in the sides of the sash.

Thereby the sash is pivotally mounted between the hanging Stiles solthat the sash can Specificationv of Letters Patent.

be arranged either in a vvertical position, in a horizontal position orin an inclined position asmay be desired.

Each han ing slfile is hollow and is provided with agchamber 8 which isopen on the outer side and which is nearly coeXtensive the stile. Theinshown.

To :balance the sash and the hanging stiles we provide each hangingstile with drums, springs Ito turn the ydrums and cords, each of w ichhas one end attached to one of the drums and the other end secured to abar 11 which is arranged in the chamlber of the hanging stile and issecured as by means of a screw 12 or the like to one side of the windowcasing. The drum 13 is arranged near the upper end of the stile, in lthechamber thereof, and is mounted for rotation on a suitable supportingaxle 14 and i-s associated spring 15 one end of which is yattached tothe drum, the other end of the attached to the axle. The other drum 16is arranged near the Ilower end of the hanging stile. in the` chamberthereof, is mounted to turn on the axle 17 and is associated with aspring 18 which is wound reversely to the spring 15 so that the PatentedMar. 18, 1919.

springs serve to turn their respective drums e 1n reverse directions.The cords 19. 2O are in practice, flat tapes and are respectivelyconnected to the drums 13, 16 and wound re-v versely thereon. f' Hencethe springs cause the drums to counteract each other and as the Stilesare raised or lowered together with the sash the drum in one end of eachhanging stile winds up i-ts cord `while the drum in the opposite end ofthe hanging stile unwinds its cord and stiles are maintained at anydesired elevation, as will be nderstood. The drums 13 and 16 and theirsprings and tapes serve in eect as checks 'for cushioning retarders.Thus when the Stiles land the sash therein are moved downwardly the`drum 16 and its appurtenanceswill perform the cushioning function,whi'le Iwhen the Stiles and sash are moved upwardly the checking orcushioning function will be performed by the drum 13 and itsappurtenances. vFrom this it'follows that the drum 13 and appurtenancescushion the stiles and sash when the same are violently moved upwardly,and the drum 16 and appurtenances will perform the same the sash andhanging function when the Stiles and eeen ere fviolen'tly inoieddownweidly.
